'EXCAVATOR OF THE SCRAPER TYPE.

Application filed September 24, 1923. Serial No. 664,405.

1 0 all whom it may concern: I

Be it known that 1, WILLIAM H. INsLnY, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented anew and useful Improvement in Excavators of the Scraper Type, of which the following is a specification.

The object of my invention is to produce' an excavator of the scraper type, embodymg a scraping excavator bucket supported upon a carriage movable upon a track which may be a cable capable of being slackened and tautened, in which the contents of the bucket may. 'be transported and dumped, at any desired point, from the rear end of the V bucket, by a continuing forward pull upon the dragline. y

The accompanying drawings illustrate my invention. Fig. 1 is a side elevation of an apparatus embodying my invention, wherein the dumping takes placethrough the rear portion of the bottom of the buck- I ct; Fig. 2, a plan of the apparatus shown in Fig. 1; Fig. 3, a partialvertical section showing the device illustrated in Fig. 1, in

, dumping position; Fig. 4, a view inpartial vertical section of another embodiment of my invention, arranged for rear end dump; Fig. 5, a view similar to Fig. 4: with the parts in dumping position, Fig. 6, an end elevation of the structure shown in Figs. 4 and 5. p a In the drawings, 10 indicates a suitable supporting track which, in the present instance, is a slack-linecable supported in the usual manner, i. e., at one end to a suitable dead man, and at the other end'to an ap-.

propriate block and tackle-supported from thevtop of a tower, and adapted to be taut-. ened and loosened. The manner of support-.; ing the track cable 10 is well known in the art and therefore not illustrated in the present application. track 10 is a carriage 11 provided, below the track 10, with a pairof supports 12-12, preferably idler wheels. Suspended from the rear end of carriage 11, at 13, is a sus pension chain 1e,the lower end of which is attached to the rear end of a, scraper bucket 15.; -Pivoted to' carriage 11, preferably near its forward end, are two arms 16-16, between the forward ends of which is mount ed a roller 17 arranged to ride upon track 10 and also to ride up on a block l8 which a swinging door or bottom section 23.

the carriage 11.

Slidably mounted on the:

. may be secured to track 10 at any desired Suspended from the forward ends of arms 16 are suspension chains 19-19, the lower ends of which are connected to the upper forward corners of bucket 15.

Mounted upon bucketv 15 at its top, and preferably at an intermediate point in its length, is an idler 20.

In the form shown in Figs. 1, 2 and 3, the bucket is provided with a fixed rear wall 21 and with a fixed bottom 22 which extends from the front edge rearwardly toward but not to the rear wall 21. The gap between the rear edge of bottom 22 and the lower edge of end wall 21 may be closed by At tached to the bottom section 23 are two up wardly converging chains 2 1 connected at their upper ends to a connector 25 which is carried by the lower end of a chain or I cable 26 passed upwardly and forwardly over which a pull may be exerted; a bridle 31 extending from the free end of the dragline to the bucket near its forward lower corners; and a line 32 extending from the free end of the dragline to the forward end of In operation, the bucket being allowed to rest upon the ground where excavation is to be accomplished, door 23 will be held closed by the weight of the bucket and a drag exerted uponthe bucket will cause it tobecome filled. The track cable 10 will then be tautened and the load will be lifted, the cable 26 being held taut by the weight of the loaded bucket and the door .23 thus held closed and the load retained in the bucket.

When block 18 is reached, wheel 17 will ride up on said block and will thus lift the forward end of the bucket to the position load may be thus controlled;

The construction shown in Figs. 4, 5" and 6' is, in most partlculars, the sameas the construction previously described. In this form, however, the bucket is provided with an end wall having; a swinging door- 4'0 as its lower portion, said door beingnormally ried by the carriage and laterally movablerelative thereto, a connection between said held closed by means of cables 4: 1, attached to the door and to the cable 26, each cable 41 being passed around an idler 42 mounted in a casing 43 arranged in a rear corner of the bucket;

In operation, this form of the invention is practically the same as the form previously described, the only di fi'erence being that the discharge of the load is through the rear end wall of the bucketinstead of through the bottom nearitsre'ar end.

I claim as my invention:

1'. A scraper excavator comprising a carriage, a scraper bucket, having a load-retaining door adjacent its rear end, a suspension connection between the rear end of the bucket and thecarriage, a member earmember and the front end ot" the bucket whereby a lateral movement in one direction willlift the front end of the bucket, and] means carried by the carriage and associated with the bucket, andconnectedwith the door, whereby the door will be held closed by saidmean'swhen the front end of the: bucket is in its lower position.

2. A scraper excavator 'comprisii'rg acarriage, a scraper bucket, having a load-retaming doorad ace'nt its rear'end, a suswhereby a lateral movement in one direct'ion will lift the front end of the bucket,

a cable attached at one endto-the carriage and at the other end" to; the bucket door,-

- and at intermediatevpointspassed oversupports onthe bucket and; on the carriage,- wherebyv the position of the bucket relative to the carriagewillcontrol the door.

3. The combination with a. slack-line track, of a carriage slid ably mounted thereon, a laterally movable element carried by the carriage, a block mounted on the track cable and engageable by said laterally movable element to cause lateral movement thereof upon movement of the carriage toward the block, a scraper bucket suspended from the carriage and from the laterally movable element, a door forming a part of the load-retaining portion ot the bucket, means connected with the carriage and door and associated with the bucket, for controlling the position of the deor by relative movement between thebucket and carriage, and a 'draglineconnected to the bucket and to the carriage;

4. The combination with a slack-line track, of a carriagesli'dably mounted thereon, a laterally movable element carried by the carriage, a bleck mounted on the track cable and engage'able by said laterally movable element to cause lateral movement thereof upon movement of the carriage toward the block, ascraper bucket suspended from the carriage and from the laterally movable element, adoor forn'iing a part of the load-retaining portion of the bucket, a cable connected at one end to the carriage and at the other end to the door and at intermediate points associated with portions of the bucket and carriagewhereby the door will be controlled-by relative movement be tween the bucket and carriage, and a dragline connected to the bucket and to the car'- riage.

5. A scraper excavator comprising a carriage, a laterally movable element carried by the carriage, a scraper bucket suspended at onepoint fromthe carriage and at another point from the laterally movable element, a Ibad enga'ged door'lorming part of said bucket, and means for controlling the o's'i'tion of said door by movement of the aterally; movable element.

6, A scraper excavator comprising a car ria'ge, a. laterally movable element carried by the carriage, a scraper bucket suspended at one" point from the carriage and at another-point from the laterally movable element, a load-engaged door forming-part of said bucket, a cableconnected-at its'opposite ends to the carriage and to thebucket door, and passed at intermediate points over por- 115 tions of the bucket and carriage.

In witness-whereof, I, VlZLL-IAM HQ Ins- LEY, have'hereunto set my hand at Indian- .apolis, Indiana, this 20th day of September, A. D. one; thousandnine hundred and t'vventy =three: V
